Grinding M Ductile

CiteSeerX - Document Details Isaac Councill, Lee Giles, Pradeep Teregowda Abstract. Ductile streaks produced during diamond grinding of hard and brittle materials have aided the subsequent process of polishing. Two novel techniques were used to study the formation of ductile mode streaks during diamond grinding primary process of germanium, silicon, and glass.

  • Ductile mode grinding of reaction-bonded silicon

    Ductile mode grinding of reaction-bonded silicon

    Ductile mode grinding can be achieved as the grain depth of cut of wheels decreases to be less than the critical cut depth of workpieces. The theoretical model gives a roadmap to optimize the grinding parameters for ductile mode grinding of RB-SiC and other ultra-hard brittle materials. Its feasibility was validated by experiments.

    Grinding of single crystal silicon may be achieved by two modes of material removal ductile mode and brittle mode. Knowing of the brittle to ductile transition point at which the grinding process changes from the brittle mode to ductile mode is critically important for the realization of ductile mode grinding. This paper uses a new single grain diamond grinding method developed recently by ...
